Thread: Next newbie stupid question?

G'Day

The vac pump on the Alt came out on the 3.9 isuu, and on nissian ptrols 4.2 lit disel, and no doubt lots of others, they work well when their not leaking oil, one of their big problems,

If you fit the bigger brakes off the 109 SIII you wont need a brake booster they'll stop the old girl well. and a much cheeper option as you will allready have them

Toyota MR2, sports car thing motor in the back electric vacume pump for the brakes up front

Despite the advice, I got one of those fancy alternators, recon, and cheap. See, the master cylinder on the 'old' rover is badly rusted while the vac assisted one on the 'new' rover is in very good condition. Will be cheaper to fit the alternator than a new brake master cylinder setup.

Now, the next question: I'm busy stripping the rover's body panels and have got to where I removed the seat base, firewall roof etc. Looking at the cross member behind the gearbox, I noticed that the prop shaft was very close to the one side of the opening (tunnel through x-member). Looking further, I noticed the engine and the gearbox off centre (horizontal) to the chassis. Looking still further, I saw strain on the engine and gear box mountings, in line with the off set of the engine and gearbox. The chassis seems straight and there is no evidence of repairs, damage etc. The front spring hanger (l/h side) is slightly bent, this pulling the spring towards the middle, causing the spring blades to splay a little.

Now, seems something is pulling the engine/gearbox assembly out of alignment. Can it be the forward spring hanger? Can it be that the axles are out of alignment with the chassis? Any opinions?

I feel a little ashamed to post this: seems I was not that clever when I bought my 'bargain'. Luckilly, when I bought the other rover, I got a complete spare chassis with it.

You need to measure the squareness of the chassis - the workshop manual details how to do this - essentially you need a nice level concrete floor, a plumb bob, and a measuring tape. The reference points marked on the floor can then be measured with a steel tape and compared to the dimensions on the chassis drawing.

Any decent panel shop should be able to pull it straight but it might cost you a few hundred dollars. Alternatively; if the damage is minor it can be a straight forward exercise to partially cut the damaged part of the chassis and bend the offending part back into line or even cut it off and replace with a piece that you have made.

You definitely need to inspect the chassis further along the longitudinal from the spring hanger; look for creases, paint damage, etc. to see how far the impact damage has travelled.

I am not sure what you mean by the engine an gearbox being off centre as they were built that way but if you can see distortion of the mounts, that suggests that the longitudinal rail has been bent probably near the damaged spring hanger.

If the damage is major, replacing the chassis is a viable option. Check your spare one carefully to see if is the same and keep the old one until the job is finished, as there is likely to be the odd bracket or fastener that you will need,
